  • Sequential triggering of series-connected resonant tunneling diodes
    Patent number: 7586427
    Abstract: One embodiment of the invention includes a quantization circuit. The circuit comprises a sense resistor configured to provide a voltage that is indicative of a digital quantization of an input voltage. The circuit also comprises a plurality of resonant tunneling diodes (RTDs) arranged in series between the input voltage and the sense resistor. The circuit further comprises a sequencing circuit arranged in parallel with the plurality of RTDs and configured to conduct a portion of a current flowing between the input voltage and the sense resistor to define a sequential order of triggering of the plurality of RTDs in response to a given magnitude of the input voltage.
